Dear all,


I do have some simple questions about light and its properties:

1. How a light ray can be divided into 2 or more sub-rays which have
the same wave length? What devices are available for this?

2. How can I change the wave-length of a given light ray? What is the
greatest precision achieved for this operation?

3. How do I measure the wave length of a light ray?

4. How many rays having different wave-length can travel (in the same
time) through an optical fiber cable?


Thanks,
Laura

Have you done anything to learn some optics on your own, in the 4
months since you last posted questions on the subject?
